ABSTRACT:
An object is to provide a blood component collection system capable of collecting a desired blood component of high quality. A blood component collection system1comprises a centrifugal separator20centrifuging blood into a plurality of components, first line21for feeding the blood to the centrifugal separator20, a second line22for releasing the blood component from the centrifugal separator20, a temporary reservoir bag26′ for temporarily reserving the platelet concentrate, a leukoreduction filter261for separating and reducing leukocyte from the platelet concentrate, and a platelet collection bag26for reserving the platelet concentrate having passed through the leukoreduction filter261. The blood component collection system1is constructed to feed the platelet concentrate in the temporary reservoir bag26′ to the platelet collection bag26through the leukoreduction filter261, and then, feed plasma and collect the platelet remaining in the leukoreduction filter261(platelet concentrate from which leukocyte have been reduced) together with the plasma into the platelet collection bag26.
